LUBRIOATING' SYSTEM.

Specification of Letters Patent. 1 Pa,tente l Sept 1 1914 Application filed octoher 7, 1910. Serial No. 585,819.

T 0 all w/wm it may concern Be it known that I, HARVEY F. MARAN- VILLE, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvement in Lubricating Sys-- tems, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to lubricating-systems of the type shown in my pending applications #545,742 filed February 24, 1910 and #569,460 filed June 29, 1910.

The objects of the present invention aregenerally to provide a system of this kind which, in addition to convenience of application to existing motor vehicles and efliciency in operation, will be economical of construction, with relative cheapness of installation.

Further objects of the invention will appear hereinafter and will be realized by the constructions embodied in the drawings forming part hereof and set forth, in their essential combinations, in the claims hereto annexed.

In the drawings Figure 1 represents a having my invention applied thereto; Fig. 2 a vertical sectional view taken through the lower portion of the crankcase having my invention applied thereto; F in. 3 a plan view of the lowerhalf of the crank case or engine base; Fig. 4. a sectional view, similar to Fig. 2, of a modified form of the invention, and Fig. 5 a plan'view of the lower portion of the crank caseor engine base shown in the preceding figure. v

Describing the parts herein by reference characters, wherein-the same numerals denote like parts in 'the different views, 1 denotes the hood'of the automobile, 2 the dash 'board, and 3 a front wheel thereof. Within the hood .and supported by the frame in the ordinary manner is-the engine,

the cylinders beingdenot-ed generally by the numeral 4. The cylinders are supported by a base or crank case comprising an upper section 5 and a lower section 6. The upper f section may be'of any ordinary standard i type, and is shown as providedwith flanges or projections to which the lower section v may be securedby means of corresponding E lateral flanges 8, the sections together form- 1 suitable clean-out openings, which may be lit externally of said chamber for receiving the surplus Oll overflowing from the foregoing chamber; also with a sediment chamber 14 depending from the chamber 12 and communicating with the lower portion. thereof. The lower section 6 is conveniently formed of light sheet metal having a rounded bottom provided with a slot 15 at the lower portion thereof said slot extending preferably the full length of the section. The sides and ends of the lower section 6 are bent or.

flared outwardly, as shown at 8, and are seated in a suitable recess in the flanges '16 of the receptacle 13, the arrangement being such that when the bottom section 6 is clamped in place, the flanged edges 8 form I in effect a gasket between the flanges 7 and 16. To one side of the slot 15 there is secured a downwardly extending plate 17 and tothe opposite side there is secured an upwardly extending plate 18, whereby said of which is considerably higher than the other, the higher edge of the port being located on that side of the port toward which the crank shaft 10 turns when the engine is going ahead. as indicated by the arrows. I

The chamber 12 will be provided with transverse partitions 20,.dividing the chamber into compartments, onefor each crank, each compartment being of sufficient depth to retain therein a quantity of oil which will cause the immersion of the lower portion of the'crank on its down stroke, even though the engine is tipped, as, for instance, when the vehicle ascends or descends a hill.

To secure lubrication by the splash system, as well as to facilitate the sweeping of the sediment from the chamber 12 into the chamber l-t. each crank will be provided with a hollow curved projection 22, the projection being curved downwardly in the direction of rotation of the shaft when driving ahead.

The sediment chamber 14 is provided with The lower section 6 is provided with a I.

plates form between them a port 19, one side conveniently arranged as follows 5 At its bottom, the chamber 141 is provided with a plate 23 having a suitable number of apertures, preferably one for each compartment. The bottom of the receptacle is provided with apertures registering with the former apertures and each aperture is of less diameter than the width of the bottom of the chamber 11. A nipple .24 is threaded into the apertures in said plate and into the bottom of the receptacle 13, thus providing a clean; out opening and at the same time anchoring the chamber 14 in place. removable plug 25 is provided.

Each conipartment, )rovided between the partitions 20, is provided with an overflow opening 125, by means of which. oil is maintained at a level to permit the dipping of the crank thcreinto. Any oil accumulating in said compartment above a certain level ma escape into the receptacle 13 and be pumped from said receptacle, through a conduit 26 and a pump 27 of any preferredconstruction, into a filter 28, which may be of the type shown in my application #569,459, filed June 29, 1910. is supplied through a pipe 29 and suitable branches 30 to the upper section 5 of the crank case, each branch being so arranged as to discharge onto the ascending cranks and thence into one of the compartments within the chamber 12.

The receptacle 13 may be provided with a suitable gage, shown as comprising a float 31 mounted in a casing 32 which communicates with the receptacle 13, said float carrying a rod 33 arranged to cooperate with a suitable index (not shown in detail).

In Figs. and '5 there is shown a modification of my invention in which the chamber containing the oil by which the cranks and other moving parts of the engine are lubricated is of somewhat different. construction from. that shown in the. preceding figures. In this embodiment of my invention, the upper section 5 and lower section 6 are connected together in the same manner as the sections in the preceding modification,-by means of flangesS clamped between the flanges 7 and 16. It is also provided with partitions 20 dividing the chamber into compartments, one for each crank 10, and each crank is shown as provided with a curved projection 22. Each compartment'of the chamber 12 is provided with an overfiow "opening 25, by means of which surplus oil may flow into-the oil receptacle 13 and thence be removed through conduit 26 and pump 27, as in the preceding modification.' The sediment receptacle 3%, however, is located at one side of and below, instead of directly beneath, the chamber 12. This receptacle communicates with'the compartments ofthe chamber 152 through ports 35, one side'of each port being located at the For each nipple 21 a From this filter, the oil lowest part of the chamber 12 and the other side being formed by a lip 36 projecting up wardly from the portion of the bot'tmn wall of 6 which is opposite the bottom wall 37. The bottom wall 37 is extended downwardly to form the bottom wall 38 for the chamber 34 and then upwardly along one of the side walls of the section 6, as shown at 39. At suitable intervals, clcan-out-openings are provided forthe removal of sedimei'it-that may be swept into the receptacle 3 1 by the rotation of the cranks 10. These clean-outopenings are conveniently formed in the manner shown in Fig. 4 and extend through the side wall of the lower section 16 and the up-turned wall 39 of the receptacle 3%. A plate 40 having threaded apertures is applied to the inner surface of the wall 39 and nipples 41 are threaded into said plate and into the side wall of the section (3. These nipples are closed by removable plugs 42, threaded thereinto.
